Piero Barone,Arnoldo Frigessi,Mauro Piccioni The type of model is called a “box” model and it is governed by ordinary differential equations. In the simplest case, there is just one first-order equation and the system is accordingly called a first-order system.

John T. Kent,Christopher Wrightow or the waste discharge varies in an arbitrary way, this is no longer so. Moreover, in many applications of box models the equations will not be so nicely linear. In general, you will need numerical techniques and these can be illustrated very well for the water quality example.

Some Limit Theorems on Simulated Annealing,ected. This is not very realistic, but you will find more about that in later chapters. The consequence is that the substance is carried with the packet of water in which it was discharged, see Fig. 4.1. If the discharge takes a time ., the length of the packet is ., where . is the flow velocity. Af

Detection of Changes in Binary Sequencestake into account that an arbitrary function, acting as initial condition, can be thought to be built up from a series of sinusoidal functions, which is called a Fourier series. As an example take a block function with length 2. (Fig. 8.1).

Aki Ishii,Kazuyoshi Yata,Makoto Aoshimaed incompressible. The reason is that the grains can move relative to one another, such that the pore volume changes. The water in the pores has to flow in or out, which takes some time. This process of consolidation is therefore time dependent. For a more comprehensive discussion see Verruijt (1983

The M/M/s Queue Length Process,s gets quite complicated, as an additional parameter (the Courant number) comes in. For practical purposes, it is often sufficient to consider diffusion and convection separately, and in that order. The procedure is then:
